[c-nsp] BGP Maximum Prefix limit on Edge routers

[Yham]

Hello Gentlemen,

I wanted to ask if this is common practice to apply Maximum prefix limit on
BGP neighborship with Internet providers from where you are getting the
entire routing table. I know its consider a best practice but want to know
if its also common.
If yes, what would be the max limit of routes? Google search tells me that
the size of the routing table today is approx 800K prefixes

Thanks
